Ukraine has disconnected the Zaporizhzhia nuclear plant from the electrical network, informs state-owned power company Energoatom in a statement Thursday.

The decoupling takes place after Russian shelling of the remaining high-voltage cables fed into the facility.

Diesel generators on site have fuel enough for 15 days, Energoatom writes.

The plant’s fifth and sixth reactors will be put into cold state.

Normally, Zaporizhzhia generates a fifth of Ukraine’s annual electricity.

In March, the power station was seized by Russian forces still controlling the site. However, Ukrainian staff are still managing daily operations.

Featuring six reactors, Zaporizhzhia is the largest nuclear plant in Europe.

Prior to the invasion, the facility employed 11,000 personnel.
